Well I had an idea and I'm wondering what you guys think about it. I think it would be nice to have this little extra option to play with your friends and use the stronghold/units/heroes etc. from the MMO mode but a loss/win wouldn't count. Basicly just showing off with your big base and goofing around with friends. (Also it shouldn't have level restrictions and could be possible only in private games).

PvE is Player vs. Enviroment, basically you play against the computer, but you still can team up with your friends and there are still other people in the world, but you don't play against other players.
